<DL class="arguments">
<DT>const char <B>*assignment</B> (in)<DD>
Info about environment variable in the format

<H3><A NAME="M5">DESCRIPTION</A></H3>
<B>Tcl_PutEnv</B> sets an environment variable. The information is
passed in a single string of the form
&ldquo;<I>NAME</I><B>=</B><I>value</I>&rdquo;.
This procedure is
intended to be a stand-in for the UNIX <B>putenv</B> system call. All
Tcl-based applications using <B>putenv</B> should redefine it to
<B>Tcl_PutEnv</B> so that they will interface properly to the Tcl
runtime.
